Edvard Munch - The Sun, 1909 _ The Sun is perhaps the greatest achievement of modern mural painting. Illuminated by the sunrays are the water of the ocean, the bare rocks of a Northern landscape, and a slim strip of verdant green that separated land and sea. A clean, straight horizon line divides the waters from sky. The great sun is all-pervasive, shinning from the heavens upon land and sea, its rays reaching out to all eternity. Inhuman itself, it is the source of all life.
